[UPDATE 3/5 @ 9:48pm]
Campbell is rehabbing at the Naruohama facilities. His workouts on March 4 included running dashes, throwing, and light one-on-one fielding practices. When playing catch, someone caught the ball for him. He also stood in on a bullpen session to help him get acclimated to live pitches.

[UPDATE 3/8 @ 12:45am]
The Tigers are not planning to rush Campbell back from the wrist inflammation. Tomoaki Kanemoto feels it might be a little while until he is ready for Ichi-gun, based on his own personal experiences. This could mean Campbell misses the start of the season.
[UPDATE 3/14 @ 2:33am]
Kanemoto told reporters he was not sure if Campbell would be ready for the start of the season. The Tigers have started exploring other options are third, just in case.
[UPDATE 3/15 @ 1:23am]
Campbell is close to resuming practices with a glove. He has done some throwing since he hurt his wrist, but no catching. He might be able to resume hitting practice some time after March 19. There is no set schedule for the time being.
[UPDATE 3/18 @ 6:22pm]
Campbell played catch at a distance of about seventy meters during workouts at Naruohama earlier today. He was able to catch the ball without any major problems. He could resume fielding practice on March 19.
[UPDATE 3/20 @ 8:42pm]
Campbell took about ten minutes of fielding practice on March 19. He fielded grounders and even made some throws to first. He told reporters he felt fine.

[UPDATE 3/22 @ 5:39pm]
Kanemoto does not think Campbell will be ready for the start of the season. He does not want to rush him and risk re-injury. This could be the seventh time the Tigers field a batting order on opening day with only Japanese players (currently six times: 1960, 1964, 1966, 1967, 1972, 1978).
[UPDATE 4/4 @ 5:22pm]
Campbell resumed batting practices on April 3 at the Naruohama facilities. He took outdoor batting practice for the first time since spring camp in February. He swung the bat thirty-five times and recorded fifteen could-be hits. He also took grounders at third and caught baseballs at first base during infield drills.

[UPDATE 4/5 @ 6:52pm]
Campbell hit three over the fence during batting practice at Naruohama today. He told reporters he felt fine and wanted to make the active roster as son as possible, but was also still a little concerned about re-injury.

[UPDATE 4/7 @ 10:11pm]
Campbell took forty swings during live outdoor batting practice Naruohama on April 6 and hit six over the fence. He told reporters he was making steady progress and that he had a pain-free session. He might be ready to play in his first Ni-gun rehab game on April 11.
[UPDATE 4/12 @ 10:52pm]
Campbell’s wrist has fully healed. Based on how the Ichi-gun team is currently performing, he may have to wait a bit before he gets called up to the active roster. He was set to play in a rehab game at Ni-gun April 11, but it was rained out. He got the start at third and batted fifth against Ni-gun Softbank today. He went 1-for-2: strike out in his first at bat in the second inning and single to right in his second at bat in the fourth inning. He handled three chances without any problems.
