[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).
