Dan Potts has been discharged from hospital after suffering mild concussion in a clash of heads at Southend United on Saturday.

The youngster was stretchered off in a neck brace and wearing an oxygen mask after being hurt in a collision with Shrimpers defender Mark Phillips late in West Ham United's 3-0 pre-season victory.

There was understandable concern for Potts' welfare as he was knocked unconscious for a short period. He was tended to by the club's medical staff and paramedics, but thankfully the 18-year-old was soon up and about and able to have a shower in the away dressing room at Roots Hall.

The left-back, who was voted Man of the Match, was taken to hospital for a precautionary scan and remained in overnight for observation before being allowed to go home on Sunday.

Potts has confirmed on social networking website twitter that he is on the mend and thanked his fans and followers for their concern and support over the past 24 hours.

"Was discharged from hospital earlier this morning. Scan and results were all OK just suffered mild concussion. Thnx again 4 all the support!" he tweeted.

The teenager produced an outstanding performance at Southend, impressing as an attack-minded left-back during the first half before moving into an unaccustomed wide midfield role in the second 45 minutes.

Potts defended with typical calm and composure, while his marauding runs and willingness to support his team-mates going forward were a constant thorn in the Shrimpers' side.

Last season's Under-18 captain will continue to be assessed by the club's medical staff before he is given the all-clear to return to pre-season training.

The son of former West Ham defender Steve Potts, Dan made four first-team appearances last season and is hoping to force his way into Sam Allardyce's thoughts on a regular basis in 2012/13.
