ALLEN PARK — It’s too soon to know how Calvin Johnson and his knee survived Sunday’s win at Cleveland.

“He was sore after the game, he’s been sore after practice,’’ coach Jim Schwartz said on Monday. “It’s too soon to really know if it’s any worse or any better than it’s been. I said it was encouraging that he was able to get on the field even though he didn’t make a lot of plays.’’

He was targeted eight times, made three catches for 25 yards and dropped two balls.

“He made a couple big first-down catches for us and affected the game,’’ Schwartz said. “They interfered with him on the one play down in the red zone because he was in position to be able to make a potential touchdown catch. Also he affected the coverage and opened up some other guys.’’

Johnson started and then was on the field for 51 percent of the offensive snaps.

Schwartz said there was no exact number of plays they had planned for the receiver known as Megatron.

"We had planned on just using him in certain situations,'' Schwartz said. "There were some things we thought he could still do, some things we didn’t want to put him in that situation.

“So it was really going by play call. Iin the second half he was feeling OK and played a little more,’’ Schwartz said.

Unable to finish

Cornerback Rashean Mathis (groin) and running back Joique Bell (ribs) couldn’t finish Sunday’s game. However, neither injury appear to be serious.

“We’re still waiting on some stuff to come in. Even after it comes in I wouldn’t anticipate it being more than short term,’’ Jim Schwartz said at his Monday press conference.

Concussion update

Tight end Tony Scheffler and running back Theo Riddick didn’t make the trip to Cleveland due to concussions suffered at Green Bay the previous game.

Schwartz didn’t have an update on either player on Monday.

They will undergo the concussion protocol set by the NFL.
