Arizona Cardinals quarterback Carson Palmer said that his decision on whether to stay or go for another season will be a “personal one” after he was diagnosed with a brain tumour.

Palmer will be out for four to six months, but the Cardinals are planning to start him back in the lineup in a few weeks.

Palmer is currently listed as day-to-day with a lower-leg injury.

The 31-year-old is one of the NFL’s best quarterbacks and has been with the team since the 2011 season.

He was the first player drafted in the first round of the 2010 NFL Draft.
