Former Oklahoma running back Brennan Clay has taken to Twitter to accuse his wife Gina D'Agostini of having an affair with his ex-college teammate and Dallas Cowboys star DeMarco Murray.

Clay appears to have posted images of the flirty text message conversations his other half and Murray had back in October during their alleged affair.

According to Gawker, one text, which was apparently from Murray, asked D'Agostini if he could have sex with her in the bed that she shares with Clay while the free agent trained with the San Diego Chargers.

Clay, who is said to have married his partner five months ago, claimed at the weekend that D'Agostini disguised Murray's number under the name 'Spray Tan'.
