Maualuga (undisclosed) has been cleared to practice after passing his physical Monday.

Maualuga missed the early portion of training camp due to an undisclosed ailment, but the veteran has now earned the green light to begin his season. Although he posted a career-low 59 tackles (33 solo) through 12 games last season, Maualuga and new teammate AJ Hawk give the Bengals a pair of solid run-stuffing middle linebackers heading into the upcoming campaign.

Maualuga (undisclosed) was placed on the Active/Non-Football Injury list Thursday, but his injury should allow him to take the practice field in short order, Geoff Hobson of the Bengals' official site reports.

Maualuga has been relatively durable in six NFL seasons, logging 85 of a possible 96 regular season games. While he's formidable against the run, his deficiencies in pass coverage don't allow reps in many third-down situations. No matter, he's posted one 100-tackle campaign, which he's complemented with six forced fumbles, five interceptions, four sacks, and two fumble recoveries over the course of his career.

The Bengals re-signed Maualuga to a three-year contract Thursday.

Maualuga is a serviceable two-down run stuffer, but his struggles in coverage often keep him off the field, thereby limiting his opportunities to pile up stats. He finished the 2014 season with just 59 tackles (33 solo) in 12 games, after recording 75 tackles (52 solo) over 13 games in 2013.

Maualuga aggravated his hamstring against the Colts and had to be carted to the locker room.

Maualuga's return is considered doubtful, and is a big loss for a Bengals' linebacker corps already playing without Vontaze Burfict.

Maualuga (hamstring) is listed as active for Sunday's game against the Saints.

Maualuga has been a hit-or-miss IDP option this season, but his return to the lineup Sunday figures to provide a needed boost to the Bengals' run defense.

Maualuga (hamstring) is listed as questionable for Sunday's game against the Saints, the Bengals' official site reports.

Maualuga was limited Wednesday and Thursday, before practicing Friday. Still, his questionable designation suggests that the linebacker may not be quite 100 percent at this stage, so a wait-and-see approach is probably in order from an IDP perspective.

Maualuga (hamstring) is planning to practice Wednesday, according to Coley Harvey of ESPN.com.

Harvey adds that Maualuga sounds confident about returning to action this Sunday against the Saints. The linebacker, who last suited up in Week 6, has recorded a total of 19 tackles in in five games to date.

Maualuga (hamstring) is inactive for Thursday's game against the Browns.

With Maualuga out, Nico Johnson figures to see added snaps at linebacker for the Bengals on Thursday.

Maualuga (hamstring) is doubtful for Thursday's game against the Browns, ESPN.com reports.

Per the Cincinnati Enquirer, Maualuga has been able to perform agility drills this week, which suggests that the linebacker could return to action as soon as Week 11's contest against the Saints.

Maualuga (hamstring) is not practicing Tuesday, ESPN reports.

Maualuga missed Sunday's game due to a hamstring ailment, which could prevent him from being ready for this Thursday's game against the Browns. Should that prove true, Nico Johnson would be expected to receive another start for the Bengals.

Maualuga (hamstring) did not practice Monday, Richard Skinner of the Cincinnati Enquirer reports.

Maualuga did not play Sunday against the Jaguars, and his status remains questionable for Thursday's matchup with the Browns.

Maualuga (hamstring) is inactive for Sunday's game against the Jaguars.

Per ESPN's Coley Harvey, Nico Johnson will start in place of Maualuga on Sunday, while Vincent Rey will fill in for fellow linebacker Vontaze Burfict.

Maualuga (hamstring) is doubtful for Sunday's game against the Jaguars, the Bengals' official site reports.

With Maualuga almost assuredly unavailable and Vontaze Burfict out as well, the Bengals' Week 9 linebacking depth will be taxed Sunday against the Jaguars.

Maualuga is expected to miss two weeks, Richard Skinner of The Cincinnati Enquirer reports.

No Maualuga and Emmanuel Lamur (shoulder) possibly in doubt means the Bengals will be very thin at linebacker when facing Justin Forsett and the rest of the Ravens' running backs. Two weeks out would mean Maualuga will return Week 10 against the Browns.

Maualuga (hamstring) is expected to miss a couple of weeks, according to Geoff Hobson of Bengals.com.

With Emmanuel Lamur unlikely to play in Week 7, the Bengals' linebacker depth will be taxed in Sunday's game against the Colts.

Neither Maualuga (hamstring) nor Emmanuel Lamur (shoulder) were able to work at Wednesday's practice.

The Bengals are awfully thin at linebacker, especially when you consider that one of the healthy linebackers is Vontaze Burfict, who briefly had to leave last week's game after another head-to-head hit.

Maualuga (hamstring) was carted off the field in Sunday's game against the Panthers, Cole Harvey of ESPN reports.

One of several injuries to the Bengals' linebacking corps, the Bengals will hope for recoveries in time for key games against the Colts and Ravens. This was Maualuga's left hamstring, the same leg as his knee injury late last season.

According to Pro Football Focus, Bengals MLB Rey Maualuga missed 14.8 percent of his tackle opportunities in the 2013 regular season.

Maualuga missed on 13-of-88 total tackle opportunities in 13 games played last season. Only Mychal Kendricks (16.5) and Derrick Johnson (16.4) missed tackles at a greater clip among inside linebackers. One season removed from being PFF's lowest graded inside linebacker out of 53 qualifiers, Maualuga again proved to be a liability last year.

Beat writer Coley Harvey suggests Rey Maualuga (knee) won't return to an every-down role once healed.

Backup Vinny Rey has been a revelation, forcing the coaches to keep giving him snaps no matter what. Over the last two games, he's racked up 27 tackles, three sacks, one interception and four pass breakups. It's the kind of production Maualuga has never been able to muster. Expect the snaps to be split fairly evenly once the Bengals come out of their bye.

Bengals MLB Rey Maualuga (knee) is tentatively expected back after the Week 12 bye.

Maualuga is dealing with a sprained MCL. It leaves the Bengals without three of their core defenders in Maualuga, Geno Atkins and Leon Hall. Backup DT Devon Still (elbow) is also sidelined. Once an elite unit, the Bengals defense is shaping up as one to attack from a fantasy perspective as they head into a Week 10 game at Baltimore.
