Eddie Howe has eased any concerns over Kieran Trippier ahead of the weekend's huge trip to Old Trafford.
Trippier has been subbed in the last two matches and at one stage was down on the ground and needing treatment during the 5-1 win over Brentford before coming off.
But Trippier left the ground in good spirits and Howe has played down any fears for the encounter against Manchester United this Sunday.

Howe said: "He just had a bit of fatigue, I think. He’s come back from England duty, where he didn’t play, and that two weeks can sometimes just knock a player’s normal routine and schedule.
"Touch wood, there’s no injury with him, but we’re just trying to look after him really – and get him through these games."
Trippier has been a key man for Newcastle since his transfer from Atletico Madrid and the full-back has helped turn the club around in the last 10 months.
