Sources: Jarrett Jack, Mario Chalmers among veterans working on comeback

Veteran guards Jarrett Jack and Mario Chalmers and seasoned forward Carl Landry are among the NBA free agents who will be looking to make a comeback to the league early in 2017, according to league sources.

Sources told ESPN.com that Jack, who has been out for the past year due to torn ligaments in his right knee suffered early in January 2016 while playing for the Brooklyn Nets, is nearing a return to full strength and will soon hold an open workout for interested teams.

Chalmers is also hopeful of making a return to the court in the near future, sources said, as he continues to recover from an Achilles tear suffered with the Memphis Grizzlies in March 2016.

Jack, 33, and Chalmers, 30, figure to attract interest from teams looking for proven depth in the backcourt. The Cleveland Cavaliers, just to name one such club, lack an experienced backup to All-Star guard Kyrie Irving.

NBA teams can start signing players to 10-day contracts as of Thursday.

Sources said Landry, meanwhile, is also planning to hold an open audition for interested teams this month to prove his NBA readiness. The 33-year-old is not recovering from an injury like Jack or Chalmers but has been a free agent since he was waived in August by the Philadelphia 76ers, who used the league's stretch provision to pay out the remaining $6.5 million owed Landry this season after acquiring him from theSacramento Kingsas part of the Nik Stauskas trade in July 2015.

Norris Cole, most recently with the New Orleans Pelicans, is another veteran guard who would be ready by next week. Cole is recovering from a hamstring injury.

The Atlanta Hawks signed Jack to a one-year minimum deal over the summer but were forced to waive him in October, when it became clear that the former Georgia Tech star needed more time to return from the knee injuries he suffered as a Net on Jan. 3, 2016.

Chalmers has been mentioned as a potential Cavaliers in-season target from the moment it became clear that fellow veteran guard Mo Williams would not play for Cleveland this season.
