SPORTS ON WEEKEND TV

This could be one of those rare weekends when all four major team sports--football, basketball, hockey and baseball--can be seen on television.

USC continues its quest for a fourth consecutive Pacific 10 Conference title against Stanford beginning at 12:30 p.m. today on Channels 7, 3, 10 and 42. UCLA has a week off from conference play and will take on San Diego State at 7 p.m. on Prime Ticket.

The highest ranked team playing on television today is No. 4 Oklahoma, which meets Texas at 1 p.m. on ESPN. The game of the day pits No. 5 Tennessee (3-0-2) against No. 9 Florida (5-0) at 4:30 p.m. on ESPN and 10:30 p.m. on SportsChannel. A week after its upset loss to Stanford and a week before its annual grudge match with Miami (Fla.), eighth-ranked Notre Dame faces Air Force at 10 a.m. on SportsChannel.

In other games involving ranked teams, No. 22 Indiana plays host to Ohio State (9:30 a.m., ESPN) and No. 24 Mississippi visits Georgia (9:30 a.m., TBS). CBS’ game matches Syracuse and Penn State at 11 a.m. (Channels 2 and 8).

Mid-October is usually not the time for must-win situations in the National Football League, but that’s where the Rams (1-3) find themselves Sunday in a 4:30 p.m. game against the Chicago Bears (4-1) on KCAL Channel 9 and TNT.

Other NFL telecasts include the Cincinnati Bengals and Houston Oilers (10 a.m., Channel 4); San Diego Chargers and New York Jets (10 a.m., Channel 39); San Francisco 49ers and Atlanta Falcons (10 a.m. Channel 8); New York Giants and Washington Redskins (1 p.m. Channels 2 and 8) and Raiders and Seattle Seahawks (1 p.m. Channel 36).
