WEEKEND TV SPORTS

Before facing the Lakers Tuesday in pro basketball’s championship series, either the Boston Celtics or Detroit Pistons will have to survive Game 7 of their rough-and-tumble Eastern Conference final, which will take place today at 12:30 p.m. on CBS (2)(8).

Dick Stockton and Tom Heinsohn will report from Boston Garden, where the Pistons have lost 17 consecutive games to the Celtics.

While a few unsportsmanlike blows have been traded in the surprisingly rugged basketball playoffs, there will be other punches thrown tonight as Mike Tyson and Pinklon Thomas vie for the WBA/WBC heavyweight title at 7 p.m. on Home Box Office cable.

There are additional hard knocks on tap--thanks to the firm clay surface at Roland Garros Stadium in Paris--as the French Open tennis tournament comes your way today at 6 a.m. on ESPN cable and Sunday at 11:30 a.m. (36)(39) and 12:30 p.m. (4).

The going also promises to be tough in hockey’s Stanley Cup series as the Edmonton Oilers and Philadelphia Flyers skate in Game 7 Sunday at 5 p.m. on ESPN.

In baseball, the Dodgers will be on their home turf at Dodger Stadium as they face the Philadelphia Phillies today at 12:15 p.m. (4)(36)(39). Sunday will bring the Angels and Toronto Blue Jays in a KTLA telecast due at 10:30 a.m. (5).

On the greens, there is coverage of the Memorial Golf tourney by way of CBS today at 11 a.m. and Sunday at noon (2).

Indoor action finds USC and UCLA squaring off in a match that will determine the NCAA men’s volleyball championship. “Sports Saturday” will be on hand today at 10 a.m. (2)(8).
