Celtic manager Tony Mowbray has boosted his attacking options by landing the Fulham striker Diomansy Kamara on loan until the end of the season.
The Bhoys also have the option to buy the Senegal international, who has not started a league game for Roy Hodgson's team since October, in the summer.
Mowbray knows the 29-year-old from their time together at West Brom, with Kamara telling the club's official website: "I'm delighted to sign for Celtic and I'm very much looking forward to joining up with the manager and my new team-mates.
"Celtic is a magnificent football club. I'll be looking to do my very best to contribute and bring the supporters success and hopefully enjoy a long future with the club."
During his time in England, Kamara scored six goals in 29 games for Portsmouth before finding the net 25 times in 72 appearances for West Brom.
His record at Craven Cottage reads 13 goals in 29 starts and 28 appearances from the substitute's bench.
Celtic have also completed the signing of Motherwell teenager Paul Slane on a four-year deal.
