But Buffalo Bills cornerback Vontae Davis trampled on that sage advice in brutal fashion by retiring during HALF-TIME of his side’s NFL match with the Los Angeles Chargers on Sunday.

Buffalo were trailing 28-6 at half-time, although they partially recovered – sans Davis – to earn a more respectable 31-20 defeat.

"This isn’t how I pictured retiring from the NFL", Davis said in a statement. No kidding…

He continued: "But today on the field, reality hit me fast and hard: I shouldn’t be out there anymore. I meant no disrespect to my team-mates and coaches.

"But I hold myself to a standard. Mentally, I always expect myself to play at a high level. But physically, I know today that isn’t possible, and I had an honest moment with myself. While I was on the field, I just didn’t feel right, and I told the coaches, ‘I’m not feeling like myself’."

His decision was later branded "completely disrespectful" by (now former) team-mate Lorenzo Alexander.
