Miami ? Michael Beasley’s first official practice with the Miami Heat ended quickly.

Beasley was struck in the chest by an inadvertent elbow during a defensive drill about 45 minutes into Miami’s first summer-league workout session Wednesday, and the No. 2 overall pick in last week’s NBA draft was taken to a doctor for observation.

Heat coach Erik Spoelstra said the move was strictly precautionary and should not affect Beasley’s availability for Miami’s five-games-in-five-days run through the Orlando summer league, which opens Monday.

“He took a shot to the chest,” Spoelstra said. “He probably could have finished if it was the regular season or something like that, but we just wanted to be safe.”

Spoelstra said he wasn’t certain which Heat summer player was the one that struck Beasley.

Later Wednesday, Miami also announced the signings of center David Padgett and guard Jason Richards. Padgett, who started his college career at Kansas University, shot 67 percent from the floor this past season at Louisville, and Richards led Div. I with 293 assists as a senior at Davidson, which lost to eventual NCAA champion Kansas in the Midwest regional final.
