Ravens center and resident genius mathematician John Urschel is retiring from the NFL after three seasons.
Urschel, 26, participated in all the team’s offseason camps, but did not report for the start of training camp Wednesday.
“This morning John Urschel informed me of his decision to retire from football,” Head Coach John Harbaugh said in a statement. “We respect John and respect his decision. We appreciate his efforts over the past three years and wish him all the best in his future endeavors.”
Urschel has not yet made any statement about his reason for retirement, but, to borrow a mathematics term, there are some strong hypotheses.
