Allen Park — Calvin Johnson jogged onto the practice field about 10 minutes before practice was scheduled to start Friday. He carried his knee brace in his hand and tossed it to the ground before he began testing his ailing right knee with a pair of trainers.
First he ran figure-eight patterns around barrels. Then he ran routes, first cutting to the right and then to the left. As expected, he looked to be most uncomfortable when he had to plant his right foot and cut to his left.
Later, after he rejoined the team for warm-ups, he ran some more routes, this time with quarterbacks throwing passes to him.
It was another positive sign for Johnson, who last week missed just his fifth game in six-plus seasons. But both he and coach Jim Schwartz have been adamant that no decision on whether he plays will be made until he tests the knee again before the game in Cleveland on Sunday.
It appears the Lions will be without two other starters. Tight end Tony Scheffler (concussion) has not been cleared to practice and isn't likely to play Sunday. Also, right tackle Jason Fox (knee) has not been able to practice.
Rookie offensive tackle LaAdrian Waddle most likely will be active. He would be the extra tackle, as well as the third tight end in the six-man offensive-line formation.
Rookie running back Theo Riddick (concussion) also hasn't been cleared to practice. His absence would mean Mikel Leshoure would be active.
