The Indianapolis Colts are unsure if Andrew Luck will play again in 2015 as he heals from a lacerated kidney.
Luck told reporters Monday that his goal is to practice this week but that he doesn't feel 100 percent yet. He said he will play again this season.
Doctors know that Luck cannot risk elevating his heart rate because it would pump more blood through his kidneys, delaying the healing process, according to medical sources.
Luck has been getting regular scans on his lacerated kidney, as often as every fourth day.
