Young midfielder Willock joined Newcastle for the rest of the season on deadline day, while Maitland-Niles headed to West Brom.
Arsenal and Newcastle began talks over a temporary switch for the England Under-21 worldwide on the final day of the January transfer window.
Newcastle has recently switched to playing a back four and Bruce said Yedlin had been marginalized because he is better as a wing back.
He is hugely experienced, with 62 caps for the US, and will leave the Premier League having played for both Tottenham and then Newcastle. He has been limited to two brief substitute appearances in the Premier League in 2021. But he has to understand that if it doesn't happen, then he gets his head down and works his way to the end of the season'.
Watson requests trade from Texans
The trade request comes after Watson was reportedly unhappy with the process used by the team to hire Caserio in early January. A day after the Texans finally found a new head coach, it's clear that work remains to be done in Houston.
'He is very keen to come here and test himself and he'll be a great addition to the squad'.
Willock is the sixth player to leave Arsenal in the January transfer window.
Mikel Arteta's side have also signed midfielder Martin Odegaard on loan from Real Madrid for the remainder of the campaign.
Yedlin moves to Galatasaray on a free transfer, but Newcastle will receive performance-related bonuses and a percentage of any potential future fee, sources have told ESPN.
