Terms of Jackson's contract were not released, general manager Mitch Kupchak said.
Jackson was in Los Angeles and was to be in uniform for Monday
night's game against the San Antonio Spurs, the Lakers said. He did
not take part in the team's shoot-around earlier in the day, so it
was unknown if he would play.
Jackson, who was waived by the Phoenix Suns on Wednesday, is a
13-year NBA veteran with career averages of 14.5 points, 4.7
rebounds and 3.3 assists in 872 games.
"Jim Jackson has been a solid player for many years in the NBA
and we feel he'll be a good addition to our team," Kupchak said in
a statement. "Being such a young team, he gives us veteran savvy
as well as the ability to play multiple positions."
Jackson, 35, was taken by the Dallas Mavericks as the fourth
pick in the 1992 NBA draft. He's played for 11 teams and had
appeared in just 27 games for Phoenix this year, averaging 3.7
points, 2.4 rebounds, 1.1 assists in 15.6 minutes.
Medvedenko, 6-foot-10, played in two games this season before
hurting his back on Nov. 9, 2005, in a game against Minnesota.
"We're sorry to have to let Slava go even though it was
unlikely that he would've been able to play the rest of the season
because of his injury," Kupchak said. "He's been a positive
addition to us for six years, including helping us win two
championships. We thank him for his contributions and wish him well."
Medvedenko was a member of the Lakers' 2001 and 2002
championship teams and has career averages of 5.4 points and 2.9
The Lakers are coming off an impressive win against defending
Eastern Conference champs Detroit Pistons, whose 48-11 record is
the NBA's best. San Antonio (46-12) comes in with the second best record.
