Jagiellonia Bialystok have been dealt an injury setback ahead of Thursday night's Europa League qualifier against Rangers after head coach Adrian Siemieniec confirmed Kamil Jozwiak will miss the first leg through injury.
The former Derby County winger suffered the problem during a recent friendly against Suduva and has been ruled out of the clash in Poland.
Speaking ahead of the match, Siemieniec admitted the experienced attacker faces a spell on the sidelines.
"As for Kamil, he is indeed injured," he said.
"He won't be available for tomorrow's match. We'll see how long his absence lasts. I wouldn't like to give a timeframe, but it's more a matter of weeks than days.
"It's an injury from the match against Suduva, and I won't be able to use him anytime soon."
Polish journalist Jakub Seweryn has since reported Jozwiak has suffered a muscle strain and is expected to be sidelined for around a month.
The 28-year-old joined Jagiellonia last September in a bid to reignite his career after spells with Derby County, Charlotte FC and Granada.
Although he has yet to register a goal or assist in 19 appearances for the Polish side, his experience would have provided another attacking option against Rangers.

Rangers praised by rival manager
Despite losing one of his senior players, Siemieniec insisted his side are relishing the challenge of facing one of Europe's most recognisable clubs.
"Rangers is a huge club, legendary," he said.
"Not just in Scotland, but in the British Isles and Europe. A club like that has to face enormous pressure and huge expectations.
"If not, everything goes the way everyone imagines, the emotions that accompany it are so extreme that some opinions might be exaggerated."
The Jagiellonia boss also revealed his coaching staff have focused on Rangers' playing style rather than recent criticism surrounding the Ibrox side.
"We have to analyse the facts and what we see on video, not focus on opinions," he added.
Siemieniec believes Derek McInnes' side will pose a major physical challenge, highlighting Rangers' intensity, aerial strength and aggressive pressing as key threats.
"It's a very demanding opponent because of its characteristics and the specifics of its football," he said.
"Through strength, physicality and the opponent's physical conditions, we should expect danger from set-pieces, pressing intensity and a team that feels very comfortable in duels.
"Many of their players have come from the Championship and everyone knows the demands of that league. The physical side of this tie will be very tough for us."
Despite identifying Rangers as favourites to progress, Siemieniec insisted Jagiellonia must remain true to their own style if they are to keep their Europa League hopes alive.

What awaits the winners?
The winners of the two-legged tie will advance to the Europa League play-off round, where either Larne or Iberia Tbilisi await, while the losers will drop into the UEFA Conference League.
