Portsmouth have signed former Leeds United defender Lubomir Michalik on a one-month contract.
The 29-year-old Slovakia international was a free agent following his departure from Carlisle United during the summer.
"I'm very happy to be here," Michalik told the club's official website. "I heard about Pompey's interest in me and I didn't have to think too long about coming here.
"I've never played at Fratton Park, so I'm looking forward to getting out onto the pitch and showing what I can do.
"Hopefully I can help the team to win a lot of games and keep some clean sheets - and if I score some goals then that is a nice extra."
Michalik will be available for Portsmouth's League One clash at home to Walsall tomorrow.
