Kansas City thought they had a future star in Justin Marsh.

The undrafted rookie was having one helluva camp, according to multiple reports. He followed two solid weeks of practice with a standout preseason debut against the Cardinals.

Unfortunately, the knee injury followed. March's surgery could keep him out 3-6 weeks, which is just enough time for his team to settle in on a replacement.

On the other hand, this tweet suggest Marsh plans on returning and reclaiming his spot amongst the linebackers.
