The Los Angeles Lakers signed undrafted free-agent center Robert Upshaw to a multiyear deal, the team announced Monday. The talented-but-raw shot blocker is expected to play at the team's upcoming training camp, with the possibility of earning a spot on the 2015-16 roster.

The 7-foot Upshaw played five games for the Lakers at this year's Las Vegas Summer League, averaging 1.4 points, 2.2 rebounds and 0.8 blocks in 11.5 minutes per game.

The 21-year-old is the 18th player on the Lakers' roster -- three more than the regular-season maximum. Teams can carry up to 20 players on their roster heading into training camp, which begins at the end of September.

Upshaw averaged 10.9 points, 8.2 rebounds and 4.5 blocks in 19 games with the University of Washington last season before being dismissed for a violation of team rules. His 85 blocks at the time of his departure led the nation and set a single-season school record.

Upshaw transferred to Washington after being dismissed from Fresno State after his freshman season for a violation of team rules.

The Fresno native had the longest wingspan at this year's pre-draft combine, measuring 7-foot-5 1/2. He also had the highest standing reach at 9-foot-5.

Upshaw makes for a low-risk, high-reward addition to a Lakers frontcourt that already includes centers Roy Hibbert, Robert Sacre and Tarik Black.
