NFL Commissioner Pete Rozelle has called a meeting for Tuesday about the trades that involve Bernie Kosar, University of Miami quarterback evidently turning pro this year. Rozelle said he had notified Minnesota, Houston, Cleveland and Buffalo to have representatives at the hearing in New York and promised a decision no later than April 23.

General Manager Ladd Herzeg of the Oilers, who traded first shot at Kosar to the Vikings before the Browns got from the Bills first call in a possible supplemental draft, meanwhile called for voiding of both deals -- "Tell everybody that Bernie Kosar will be in the April 30 draft and let everybody start from scratch." . . .

Larry Mason, subbing after Mike Rozier left in the second quarter with a hand injury, ran for 100 yards on 16 carries to lead the Jacksonville Bulls to a 28-17 USFL victory last night over the visiting San Antonio Gunslingers. The clinching touchdown came on a 49-yard drive begun when Van Jakes intercepted a Gunslingers pass. The San Antonio coaching staff protested the interception, so the officials viewed a television replay and verified their call. HORSE RACING
