The Pittsburgh Penguins were very active with professional tryouts (PTO) in 2023. They signed forwards Austin Wagner, Colin White and defenders Libor Hajek and Mark Pysyk to PTOs before training camp. Then, later into the season, Jesse Puljujarvi began his journey back from double hip surgery on a PTO.
The results turned out pretty decent too for the Pens. White and Puljujarvi were eventually signed to NHL contracts, though White was waived during the season and claimed by Montreal. Hajek was signed to an AHL contract by Wilkes-Barre before deciding to head back to his native Czechia.
