Allen Park – Lions coach Jim Schwartz said Monday it was too soon to tell how receiver Calvin Johnson's ailing right knee responded to his 34 offensive snaps Sunday against the Browns.
"He was sore after the game, but he's sore after practices, too," Schwartz said. "It's too soon to really know if it was any worse or any better than it's been. It was encouraging that he was able to get on the field for us."
Running back Reggie Bush said after the game that he didn't think Johnson did any further damage to the knee.
"He made some plays even though he wasn't 100 percent," Bush said. "That was pretty amazing. Not a lot of people can do that. The important thing is he didn't have any setbacks. I hope he can continue to get better."
Schwartz said the team was still awaiting more medical information on running back Joique Bell (ribs) and cornerback Rashean Mathis (groin). Both were unable to finish the game Sunday.
"Even when the stuff does come in, I wouldn't anticipate it being more than short term," he said.
Schwartz was asked if the team was considering putting tight end Tony Scheffler on IR. Scheffler and running back Theo Riddick, both dealing with concussions, didn't travel with the team Sunday.
"Both of those guys are still being evaluated," Schwartz said. "That's all I have to say."
The Lions were working out some tight ends on Monday.
"I don't think one has direct influence on the other," Schwartz said when asked if there was a cause and effect there. "That decision (to work out tight ends) will be made regardless of Tony's situation."
