Jerry Rice, the NFL's all-time touchdown and receiving record holder, has undergone surgery to repair the left kneecap which was broken across the middle during San Francisco 49ers' 34-17 win over Denver on Monday. The wide receiver had made a scoring return to action 15 weeks after surgery for torn left knee ligaments. But he cracked his left knee cap catching a 14-yard touchdown pass and will now be out for the next eight to 10 weeks.

Scottish Claymores have appointed two new defensive coaches as they prepare for the 1998 World League season. The NFL veteran Myrel Moore and the former Oakland Raiders player Richard Rodgers are teaming up with the head coach Jim Criner.
