OTL: Testing The Limit (8:17)

Georgia offensive lineman Kolton Houston has been fighting with the NCAA to get back on the field for three years.

He finally got some good news on Thursday when the NCAA reinstated him.

Houston's story was chronicled on ESPN's "Outside the Lines" (above), and he never gave up hope of playing for the Bulldogs. Houston first failed an NCAA random drug test shortly after enrolling at Georgia in 2010, causing the NCAA to rule him ineligible because of steroid use. Houston and Georgia's medical staff insisted that his positive drug test stemmed from a steroid injection following a shoulder surgery prior to enrolling at Georgia. The steroid, however, seemed to be stuck in Houston's system, and the levels never decreased enough for the NCAA to rule him eligible until just recently.

"This is the best birthday present I've ever had," Houston said in a university statement. "I had almost reached the point where I thought this situation would never end. When I got the call, I broke down and cried for about 30 minutes. I had that much emotion stored up and it felt good to get it out. I'm ready now to show what I can do."

Houston, who turned 22 on Thursday, joins a Georgia offensive line that was already returning its top eight lettermen from last season. Houston worked as the Bulldogs' starting right tackle in the spring of 2012 and gives them even more flexibility up front going into this season.
