Matt Johnson to have MRI on ankle

CANTON, Ohio -- Safety Matt Johnson will have an MRI on his left ankle when the Cowboys return to Oxnard, Calif., on Monday morning.

Johnson was hurt in the second quarter of Sunday’s 24-20 win against Miami as he tracked down wide receiver Chad Bumphis on a 45-yard gain. Johnson landed awkwardly as he tackled Bumphis and limped to the sideline.

X-rays during the game were negative.

Also, defensive end Ben Bass was kicked in his left knee after defensive end Kyle Wilber pressured quarterback Matt Moore. Bass was examined by the medical staff and did not return to the game, but owner and general manager Jerry Jones said he was told it’s not believed to be serious.

Running back Phillip Tanner had X-rays on his left arm. He left in the first quarter but was able to return to the game. After the game, Tanner said he was fine.

Rookie wide receiver Terrance Williams did not play against the Dolphins after suffering a concussion in practice Friday but still made the trip to Canton.

“I’m going to tell you day by day, but we don’t think what he has is a serious issue,” coach Jason Garrett said of Williams' status.
