The Trail Blazers are on the verge of signing 6-foot-11 forward

, a move that would add to their front court depth for the stretch run.

Johnson, who has been playing for the Dakota Wizards of the NBA Development League, will be called up by the Blazers and signed for the rest of the season, a source with knowledge of the situation told The Oregonian.

The Blazers signed Johnson to a 10-day contract in January, when they were granted a hardship exception by the NBA, and he later signed a 10-day contract with the Boston Celtics. But, with 17 games left in the regular season for the Blazers, this would be his longest chance in the NBA.

Johnson, who played in six games during his brief NBA stints earlier this season, averaged 16.2 points, 9.2 rebounds and 2.8 blocks in 35 games this season in the D-League.

His signing would bring the Blazers’ roster to 15 players — which includes Jarron Collins, whom the Blazers signed to a second 10-day contract last week.
