Appearing on The Big Show on Wednesday afternoon, Red Sox manager Bobby Valentine responded to ESPN analyst Buster Olney's contention on Mut & Merloni that there was discontent in the clubhouse by saying it was "absolutely ridiculous."

Ryan Kalish will make his return to the Red Sox lineup as they play the third game of their series with the Tigers at Fenway. Kalish hit .217/.238/250 in 60 at-bats with the Sox before returning to the minors on July 7. He was recalled after Ryan Sweeney injured his hand punching a dugout wall during Monday's game.

With Kalish in right, Cody Ross will assume designated hitter duties and Jarrod Salatlamacchia will take over behind the plate for pitcher Aaron Cook. Here's the rest of the lineup that will face Tiger starter Rick Porcello:

Appearing as a guest on The Big Show on Wednesday, Red Sox manager Bobby Valentine said he didn't think Josh Beckett would require a trip to the disabled list after his back tightened up in the third inning of Tuesday's game against the Tigers.

"I doubt that. It doesn't seem like a DL," Valentine said. "But again, when Josh left last night he was tight. The trainer's report so far today and Ben [Cherrington] had talked to Josh, was it just a little tight and we'll take it, as we do, day by day."

Buster Olney joined Mut & Merloni for his weekly appearance on Wednesday afternoon and said Josh Beckett's name likely will still be associated with trade rumors in August.

The July 31 trade deadline has passed, but teams can still place players on waivers and trade them if they go unclaimed.

According to multiple major league sources, one potential deal discussed by the Red Sox and Rangers prior to the non-waiver trade deadline included a package that would have sent Josh Beckett, Jacoby Ellsbury and Kelly Shoppach to the Rangers. It is unclear what player compensation the two teams discussed going from Texas to the Red Sox in such a deal.

Sports Illustrated baseball writer Tom Verducci joined Dennis & Callahan on Wednesday morning to talk about how the Red Sox season shapes up post-trade deadline.

The Red Sox were quiet leading up to Tuesday's deadline, making no major moves.

Red Sox starter Josh Beckett, who was pulled from Tuesday's starter after 2 2/3 innings when he experienced back spasms in part due to a slippery mound, said that while the injury forced him out of his team's 4-1 win over the Tigers, it was not as severe as the back injury he suffered in similiar circumstances in New York in 2010.

Jacoby Ellsbury worked a bases-loaded walk off Tigers ace Justin Verlander to break a 1-1 tie as the Red Sox scored four times in the fourth in a 4-1 rain-shortened win over the Tigers at a soaked Fenway Park. 

Red Sox starter Josh Beckett left with two outs in the third inning of Tuesday night's game against the Tigers with what the team classified as a back spasm. He was replaced by reliever Clayton Mortensen.

Beckett had retired the first eight batters before Omar Infante reached on a slow roller to shortstop. The starter then proceeded to hit Austin Jackson and issue back-to-back walks to Quintin Berry and Miguel Cabrera to force in the game's first run.

Red Sox reliever Scott Atchison received discouraging news, as an MRI on his right elbow revealed the possibility of a torn ulnar collateral ligament that would require Tommy John surgery, according to manager Bobby Valentine. Atchison will seek a second opinion.
