Celtic winger Mikey Johnston is poised to join West Brom on loan until the end of the season.

This is according to The Telegraph who claim that the Republic of Ireland international "is set to undergo a medical at the English Championship side ahead of proposed move".

Johnston has two goals and as many assists in 12 appearances for the Scottish Champions so far this campaign.

He has struggled with injuries during recent years and spent last season on loan at Portuguese side Vitoria de Guimaraes.

A graduate of the Lennoxtown academy, the 24-year-old made his debut for Celtic in 2017 during Brendan Rodgers' first spell in charge.

Johnston has played 93 times for the Hoops in total, providing 25 G/A in that time.

Meanwhile, Celtic are 'open to offers' for lifetime servant James Forrest, it has been claimed.

talkSPORT reporter Alex Crook states that it's set to be a busy day at Parkhead in terms of outgoings.

David Turnbull is set to complete his £2m move to Championship side Cardiff, while West Brom are closing in on Mikey Johnston.

However, the shock update regarding the Hoops is that Forrest - the club's longest-serving player - could well be away.

Crook tweeted: "Busy day of exits at #Celtic with David Turnbull set to join Cardiff City and Mikey Johnston moving to #WBA on loan.

"Also told they are open to offers for long-serving James Forrest."

Forrest, 34, has struggled for game time since Brendan Rodgers returned as manager in the summer. 

He's featured just 18 times this campaign, mainly from the bench in cameo appearances. 

Forrest's current Celtic contract is due to expire in the summer of 2025. The Scotland international has won 22 major trophies at Celtic.

Meanwhile, Alan Brazil has made an astonishing claim regarding Brendan Rodgers' happiness at Celtic.

The Hoops-daft radio host this morning stated that he's heard 'rumours' about the Irishman's frustrations in the job at Parkhead.
