Lions LG Rob Sims is recovering from offseason surgery.

Sims hinted he's recovering from multiple clean-up type procedures, but nothing serious. Per the Detroit Free Press, the Lions have taken a "long look" at third-year undrafted free agent Rodney Austin in Sims' absence. Now 30, Sims is coming off a mediocre year, but should keep his starting job for 2014.

Lions LG Rob Sims hopes to sign a contract extension this season.

Sims, 30, is set to make $2.2 million in the final year of his contract. He struggled to play above replacement level last season, grading out negatively in run-blocking by Pro Football Focus. Sims wants to finish his career in Detroit and could be open to a team-friendly deal.

Lions LG Rob Sims has been limited during OTAs.

It means third-year undrafted free agent Rodney Austin has been running as the starting left guard. Sims' ailment is not believed to be major, while he hasn't missed a start since signing with the Lions in 2010. Going on 31, Sims graded out in the middle of the pack in Pro Football Focus' guard ratings last season.

Lions LG Rob Sims says he's "right where (he wants) to be" with his weight after gaining 15 pounds.

Sims admits the weight gain will sap his quickness. "Of course I'm a lot quicker at 290 pounds, but I need a happy medium between being as quick as I can be and being as strong as I can be," he said. "I am right where I want to be." The Lions were apparently on board with Sims bulking up, but more in the range of 5-10 pounds than 15-20. Sims played near 300 in 2011, and will likely tip the scales in the vicinity of 310 this season.

Lions LG Rob Sims showed up to the team's offseason program 20 pounds heavier than he was last season.

Lions OL coach George Yarno insists the weight gain was on purpose. "He wanted to just be a little firmer in the run and the pass," Yarno said. "He was right at 300 (last year), and I think he wants to be in the 315-320 range to have more mass in order to get movement in the run game." Yarno did admit Sims has "got to get in shape," and is "not ready to play a game right now."

Lions signed LG Rob Sims to a four-year extension through 2014.

Left tackle Jeff Backus' pass-blocking whiffs have sidelined Matt Stafford for a second straight year, but Sims isn't to blame. He's solidified a longtime trouble spot at left guard in Detroit with consistent performance both on the ground and when the Lions have gone to pass. The 26-year-old was a value pickup in the offseason. The Lions got him for a fifth-round pick.

The Lions have given no indication that they plan to extend LG Rob Sims' contract after dealing for him on Monday.

Sims, the 15th different guard to start between left tackle Jeff Backus and center Dominic Raiola, hopes to stay in Detroit. He'll have to prove early in the season that he's the solution at left guard before the Lions lock him up.

Lions acquired OG Rob Sims from the Seahawks in exchange for undisclosed compensation.

Sims, 26, will likely move into the Lions' starting lineup immediately at left guard. Though somewhat injury prone, Sims has racked up 31 starts over the last three seasons and is a low-risk acquisition because he's only under contract through 2010 at a mere $1.101 million. 2009 LGs Manuel Ramirez and Daniel Loper may now be left fighting for one roster spot in Detroit.

Profootballtalk.com reports that Seahawks restricted free agent OG Rob Sims could be traded by as soon as this week.

Chicago and Detroit are considered his most likely two destinations. Sims signed his tender late last week, so he can be shipped off immediately. The Seahawks have made it abundantly clear that he won't be returning to Seattle.
