CHICAGO -- The Pittsburgh Penguins have three injured defensemen, so they did something to make up for that before the NHL Trade Deadline passed Wednesday.
Pittsburgh acquired 39-year-old defenseman Mark Streit and 23-year-old defenseman Frank Corrado in separate trades.
Streit came from the Tampa Bay Lightning for a fourth-round pick in the 2018 NHL Draft, and Corrado cost Pittsburgh forward Eric Fehr, defenseman Steve Oleksy and a conditional fourth-round pick in the 2017 NHL Draft.
On Feb. 23, the Penguins acquired defenseman Ron Hainsey in a trade with the Carolina Hurricanes.
"That's what our big need was with all these injuries," Pittsburgh general manager Rutherford said before the Penguins played the Chicago Blackhawks at United Center. "We added three defensemen here within the last week, two experienced NHL guys and Frank Corrado, [who] we think with a little work in there with our development group and coaching in Wilkes-Barre [is] a guy who's going to play on our team at some point."
Streit had 21 points (five goals, 16 assists) in 49 games for the Flyers this season averaging 19:23 a game, including 2:32 on the power play. He can become an unrestricted free agent on July 1.
"He's obviously a veteran guy," Penguins coach Mike Sullivan said. "Mark's a good player. With some of the injuries we have, I think [the front office] was looking to try to improve our depth on defense so that we have the best chance to succeed moving forward."

Streit has 428 points (95 goals, 333 assists) in 765 NHL games over 11 seasons with the Flyers, New York Islanders and Montreal Canadiens. He has 13 points (four goals, nine assists) in 31 Stanley Cup Playoff games.
"His experience [was key]," Rutherford said. "We had a lot of information on him, his character. We know what a great guy he is. He can play both sides, and right now in the early going he can play with one of our younger guys. So that was an important addition."
The Penguins played Wednesday without defensemen Kris Letang (upper body), Olli Maatta (hand) and Trevor Daley (knee). Daley is on long-term injured reserve, and he and Maatta might be out until the playoffs.
Letang, who's missed three games, has no timetable for a return. Corrado will report to Wilkes-Barre/Scranton of the American Hockey League.
"Their [health] status is the same, but it's [the] same that two of them could be out until playoff time, and we don't really know how long Kris is going to be out," Rutherford said. "So, those are three important guys. It was important that we added the guys that we did."
The Penguins could have eight defensemen with NHL experience to pick from in the playoffs.
"It will make for difficult decisions," Sullivan said. "My experience of going through it in the past is that depth gets challenged when you have high expectations and you're trying to make a deep run. So we feel good about the depth we have."
