Mark May, Washington Redskins starting offensive guard, practicing today for the second time since he suffered a partial tear of his right triceps 19 days ago, said he felt sharp pain in the triceps area during this morning's practice.

"They told me it would be painful when I first came back. I didn't think it would hurt this much," said May, third-year lineman who won the Outland Trophy at the University of Pittsburgh in 1980. May said he felt pain in the triceps when he blocked defensive tackle Pat Ogrin during a drill.

"Mark may have done too much work this morning," said Bubba Tyer, team trainer. "It's not completely healed. Soft tissue takes about six weeks to heal. In football, you don't have six weeks to give it. So you try to reach a happy medium. He'll have to take it a little slower the next couple days and we'll give him (ice) treatments."

Tyer added, "He didn't tear it (right triceps) today. If he had, I think there would have been more swelling."

Said May, "I don't think I came back too early. I'm the type of player where if I don't get in my reps (repetitions during drills), than my techniques will drop off. And this is a game of techniques . . . I just shouldn't have tried to kill the guy (Ogrin). I should have been smarter."

Rookie cornerback Darrell Green played with the first team today, replacing LeCharls McDaniel, a third-year player, at left cornerback. Asked if there was any significance in the move, Richie Petitbon, coach of the defense, shrugged and said, "I guess" . . . Tight ends Rick Walker (bruised left thigh) and Don Warren (slight pull of left hamstring) did not practice today and are listed as day to day.
