I had THAT EXACT INJURY when I played, including the tear, but it healed on its own. It happened in a game in October, and I was back running indoor track sprints that winter.I have seen Love's knee injury described in various stories as an MCL sprain. I don't know that I have heard Jeremiyah himself describe his injury, though. I have never read that surgery was ever considered. A severe sprain can involve some tearing of the ligament, but usually non-surgical intervention (rest and PT) will allow it to heal. Sounds like JL had a bad MCL sprain to me.
I was a senior in HS when it happened and played football with no ill effects in college for two years afterwards. My speed stayed the same.
If that's all it is, IT SHOULDN'T BE A PROBLEM.
