Injuries to Cleveland Browns quarterback Bernie Kosar and fullback Kevin Mack make them questionable for Sunday’s regular-season ending game, a crucial engagement with the Houston Oilers.

Kosar and Mack, who returned from Monday night’s defeat at Miami, limited their activities Tuesday to exams by the team doctor.

Kosar was knocked out of the Miami game with a sprained left knee with 9 minutes 17 seconds left. Mack missed the game with a persistent knee injury.
