Ryan Sweeney (concussion) has yet to be cleared for any baseball-related activities.

"Sweeney has no activity," Red Sox manager Bobby Valentine said. "[We need to] allow [his] symptoms to subside." It's not surprising, given that Sweeney was just placed on the DL Tuesday. He's eligible to return on May 28, but it's up in the air as to whether he'll be ready at that time.

Red Sox placed OF Ryan Sweeney on the 7-day disabled list, retroactive to May 20, with a concussion.

Sweeney suffered the head injury and whiplash Saturday while making a diving catch. It's not clear how long he'll be out. He failed a concussion test given Monday.

Ryan Sweeney (quad) will start hitting on Friday and could be ready for game action sometime over the weekend.

Sweeney has been out since being pulled from Monday's Grapefruit League game after straining his left quad. "I don't want to push it. I'd rather have to deal with it now than during the season,'' he said. As long as he does indeed return in a day or two, he'll be fine for the start of the season.

Ryan Sweeney was pulled from Monday's Grapefruit League game against the Marlins with a left quad strain.

Sweeney was 0-for-1 in the contest and is now 1-for-12 for the spring. The 26-year-old is expected to see a considerable chunk of the playing time in right field this year in Boston after being acquired alongside Andrew Bailey in a December trade with the A's. This quad issue may set Sweeney back a couple of days, but it's still early enough for him to heal in time for the start of the season.

Red Sox and OF Ryan Sweeney avoided arbitration by agreeing to a one-year, $1.75 million contract.

Sweeney, who was acquired from the Athletics last month in the Andrew Bailey deal, earned $1.4 million last season while batting .265/.346/.341 with one home run, 25 RBI and a .687 OPS over 299 plate appearances. The Red Sox will likely sign add an outfielder prior to spring training, but Sweeney still figures to get plenty of playing time in right field.

Sweeney might seem like a throw-in, but he's actually a nice fit for Boston. The 26-year-old is a very good defensive outfielder and should have no trouble with Fenway Park's sometimes-tricky right field. The Red Sox will likely try to find him a platoon partner to face left-handed pitching.
