Veldheer made headlines in training camp last season when he contemplated retirement, but said in early January that he planned on playing in 2018.
Though the Broncos are hopeful the changes eliminate numerous 52 sacks on their quarterbacks previous year (tied with Arizona for the third-most in the NFL), they leave the right guard spot in question.More news: Naspers sell-off casts shadow over Tencent Q4 report

Veldheer, pronounced vell-DEER, started 46 games at left tackle for Division II Hillsdale College (2006-09), where he was named a 2009 AFCA First-Team All-America selection. He signed a five-year, $35 million contract in March 2014 after four seasons with the Oakland Raiders.
He is owed a base salary of $6.5 million for 2018.
During his first eight seasons, Veldheer started 101 games along the offensive line (91 at LT; 9 at RT; 1 at C) and allowed just 28 sacks (STATS INC). That made it 11 total games Veldheer had missed in the last two seasons after he was ruled out for the rest of the 2016 season when he tore his right triceps in Week 8.
