The Thunder have finalized their training camp roster by adding Walker Russell Jr. to the squad, the team announced today (Twitter link). The move gives Oklahoma City 19 players under contract heading into camp.
Russell, who turns 30 this weekend, went undrafted in 2006 and has bounced around since then, playing for a number of teams overseas and in the D-League. He finally made his NBA debut last year for the Pistons, signing a non-guaranteed contract with the team that eventually became guaranteed. In 28 games for Detroit, the point guard averaged 3.0 PPG and 2.1 APG in 12.8 MPG.
Terms of Russell's deal with the Thunder aren't known, but it's almost certainly a non-guaranteed summer contract.
