After a month on the sidelines, Rockies' shortstop Troy Tulowitzki is sensing that his return to the field is close to occurring, according to The Denver Post.

He will undergo a few more days of strength tests on his strained left quadriceps before beginning a rehab assignment.

"It's getting really close if there are no setbacks," Tulowitzki said.
