Bears running back Marion Barber didn't practice Monday, and his left calf had a black sleeve on it.

Since key players generally make a cursory appearance in the preseason finale, Barber likely won't play against the Cleveland Browns. But indications are, the Bears got encouraging news about Barber's calf injury.

The full extent of his injury isn't known. But, Bears defensive tackle Anthony Adams has missed practice since earlier this month with a calf injury. His, though, required a walking boot.

Against the Tennessee Titans on Saturday, Barber entered the game toward the end of the first quarter, catching one pass for eight yards and converting a third-and-1 by gaining two yards.

But he left the field, and he was ruled out for the remainder of the game around halftime.

Barber has established himself as the team's No. 2 running back after a strong training camp and preseason during which he's averaged 4.6 yards per carry.

Meanwhile, the Bears also are hopeful about tight end Desmond Clark. He took a shot directly to the left knee from Titans safety Anthony Smith. Clark was clearly in pain, and he was taken off the field on a motorized cart.

Clark, though, later said on his Twitter account that the hit wasn't as bad as it looked and that he was confident he would return to the field "soon."
