Sounds like Ted Karras redux as a day 3er backup who can play both guard and center.
I also wonder if he's a potential replacement for Andrews at center who I believe is up for a new contract soon
Hjalte Froholdt (pronounced yell-duh fro-holt) came to the United States from Denmark as a foreign exchange student his sophomore year in high school. He returned to Denmark for one year before coming back to America to attend the IMG Academy in Florida (to play for former Heisman Trophy winner Christ Weinke) his senior year. Despite limited experience, his promise was not lost on colleges or recruiting services, as he was ranked among the top 20 defensive linemen in the country. Froholdt played in 10 games on defense for Arkansas in 2015 (three tackles) before moving to the other side of the line the following spring. He started all 13 games at left guard in 2016, and then all 12 games at that spot as a junior, not allowing a sack and incurring only two penalties. Froholdt started his senior season at center, starting the first three games there before switching back to left guard for the final nine contests.

Overview
Froholdt has primarily lined up at guard, but a move to center might give him his best shot as a pro. He has good power to absorb and neutralize at the point of attack, but there just aren't enough wins as an in-line blocker due to his lack of push. Froholdt also struggles to protect his edges through foot quickness or functional power and he should be able to get the help he needs at center. His ability to play both guard and center strengthens his case to become a solid backup who can step in and start in a pinch.
